Andrew F. Laine – 1st expert on this subject based on the ideXlab platform

  • In the Spotlight: Biomedical Imaging
    IEEE Reviews in Biomedical Engineering, 2013
    Co-Authors: Andrew F. Laine


    In this spotlight, advances in four topics in Biomedical Imaging are described. This does not begin to cover all of the advances in the field, but include topics that remain the most compelling in terms of mortality (cardiovascular disease) and increasing concern (Chronic Obstructive Pulmonary Disease, (COPD)). We also report on some very exciting progress in making methods of MR spectroscopy more reliable and robust, thus suitable for wider clinical use. Finally, we describe recent developments in nuclear and molecular Imaging related to diagnosis and treatment of cancer.

  • In the Spotlight: Biomedical Imaging
    IEEE Reviews in Biomedical Engineering, 2008
    Co-Authors: Andrew F. Laine


    This article reviews some of the more recent advances and trends in the area of Biomedical Imaging. Real-time multimodality Imaging and image-guided interventions are presented as well as other fast growing areas of interdisciplinary research and development. Segmentation, registration and spatial-temporal integration in medical image processing are also discussed.

  • Extended-cavity semiconductor wavelength-swept laser for Biomedical Imaging
    IEEE Photonics Technology Letters, 2004
    Co-Authors: C. Boudoux, M.c. Pierce, J.f. De Boer, G.j. Tearney, B.e. Bouma


    We demonstrate a compact high-power rapidly swept wavelength tunable laser source based on a semiconductor optical amplifier and an extended-cavity grating filter. The laser produces excellent output characteristics for Biomedical Imaging, exhibiting >4-mW average output power, 80-dB noise extinction with its center wavelength swept over 100 nm at 1310 nm at variable repetition rates up to 500 Hz.

  • dual modality fluorescence and full field optical coherence microscopy for Biomedical Imaging applications
    Biomedical Optics Express, 2012
    Co-Authors: Egidijus Auksorius, Yaron Bromberg, Rūta Motiejūnaitė, Alberto Pieretti, Emmanuel Coron, Jorge Aranda, Allan M Goldstein, Brett E Bouma, Andrius Kazlauskas, Guillermo J Tearney


    Full-field optical coherence microscopy (FFOCM) is a high-resolution interferometric technique that is particularly attractive for Biomedical Imaging. Here we show that combining it with structured illumination fluorescence microscopy on one platform can increase its versatility since it enables co-localized registration of optically sectioned reflectance and fluorescence images. To demonstrate the potential of this dual modality, a fixed and labeled mouse retina was imaged. Results showed that both techniques can provide complementary information and therefore the system could potentially be useful for Biomedical Imaging applications.

  • numerical study of wavelength swept semiconductor ring lasers the role of refractive index nonlinearities in semiconductor optical amplifiers and implications for Biomedical Imaging applications
    Optics Letters, 2006
    Co-Authors: A Bilenca, Guillermo J Tearney, Brett E Bouma


    Recent results have demonstrated unprecedented wavelength-tuning speed and repetition rate performance of semiconductor ring lasers incorporating scanning filters. However, several unique operational characteristics of these lasers have not been adequately explained, and the lack of an accurate model has hindered optimization. We numerically investigated the characteristics of these sources, using a semiconductor optical amplifier (SOA) traveling-wave Langevin model, and found good agreement with experimental measurements. In particular, we explored the role of the SOA refractive-index nonlinearities in determining the intracavity frequency-shift-broadening and the emitted power dependence on scan speed and direction. Our model predicts both continuous-wave and pulse operation and shows a universal relationship between the output power of lasers that have different cavity lengths and the filter peak frequency shift per round trip, therefore revealing the advantage of short cavities for high-speed Biomedical Imaging.
